Application:
  • dry and humid temperature measurement, determining the relative humidity, dew point temperature and required overheating, allows you to check whether the system is working right amount of refrigerant.
Description:
Fieldpiece head is ARH4 hygrometer (hygrometer) with a group psychrometers, that is made of dry and humid temperature measurement, and determines the dew point temperature or condensation of water vapor contained in the air. These parameters allow you to precisely determine the value of ARH4 relative humidity to ± 1% RH. Another useful parameter that determines the WB, the device is assumed superheat temperature (superheat).

Fieldpiece ARH4 has a pair of sensors: thermistor and hygrometer, estimating the temperature and humidity. Programmed into the device calculates psychrometric tables meteorological data obtained. To achieve absolutely exact values, after exposing psychrometer with exposed sensors on the outside, wait a few minutes for the sensors zbalansowały difference in weather conditions before joining the measurements.

Like other snap heads Fieldpiece, psychrometer can be connected directly to the universal metrics HS series. For other models, use test leads or connector holder ADLS2 AHDL1. To read the parameters, simply on the meter set the range for mVDC

Highlights:

psychrometr as an additional head can start working in conjunction with any tools Fieldpiece, as well as with other electronic meters mVDC working on the field and enabling connection via pin jack (in the holder AHDL1) head is designed for HVAC / R: Only a few psychrometers measure the wet bulb temperature (wet bulb) and independently convert this value to give the dew point physical separation in a separate group head of digital sensors meter electronics, has ensured the complete insensitivity of measurements to electronic interference the ability to easily change the accepted system of measurement (metric or British) automatic shut-off after 10 minutes of inactivity, prolonged battery life
